Method of desulfurizing gases
A method is described for desulfurizing gases containing hydrogen formed by the incomplete combustion of sulfur containing hydrocarbons at high temperature in which gases the sulfur is mainly in the form of one of hydrogen sulfide and sulfur carbonyl whereby the sulfur is removed to sufficiently low levels that when combustion of the gases is completed the gases emitted into the atmosphere have a sulfur content which is less than one pound of sulfur per million British thermal units produced by combustion of fuel or its equivalent comprising the steps of: a. Controlling the incomplete combustion of the sulfur containing hydrocarbons so that the ratio of carbon monoxide to carbon dioxide (CO/CO/sub 2/) ratio at standard conditions (32/sup 0/F and one atmosphere pressure) is greater than one; and b. Reacting the gases whose CO/CO/sub 2/ ratio is greater than one and whose sulfur content is in the form of one of H/sub 2/S and sulfur carbonyl (COS) with cerium oxide.
